• Rio Tinto and Glencore confirmed early-stage discussions on a potential transaction with no firm offer.
• Rio Tinto must declare its intention to bid, or not, by Feb. 5, 2026, under UK takeover rules.
• Analysts said a deal could create the world’s largest mining group with a combined market value near $207 billion.

Global miners face rising demand for strategic metals and persistent supply constraints, prompting large groups to seek scale and portfolio strength.

Against this backdrop, a merger between Glencore and Rio Tinto could create the world’s largest mining group.

Rio Tinto and Glencore confirmed this week that they have entered preliminary discussions regarding a possible combination of some or all of their businesses.

Both companies stressed the exploratory nature of the talks and said no firm offer exists at this stage, either in principle or in structure.

What the Companies Say

In separate statements, the two groups said no certainty exists that the discussions will lead to a transaction.

The companies also said any potential deal would remain subject to strict regulatory approval.

Glencore said the scenario currently under consideration would involve its acquisition by Rio Tinto through a court-approved scheme of arrangement, a structure commonly used for UK transactions.

Rio Tinto confirmed the preliminary discussions and said it reserved the right to adjust the form and composition of any potential consideration if it proceeds with an offer.

The timeline now follows a defined regulatory framework. Rio Tinto has until Feb. 5, 2026, at 5:00 p.m. London time, to announce either a firm intention to make an offer or a decision not to proceed.

African Assets and Market Context

The discussions come as investors focus increasingly on copper and other metals critical to electrification, energy infrastructure and the energy transition.

Sustained copper price gains and concerns over global supply growth have increased the strategic value of large-scale mining assets.

In this environment, consolidation has emerged as a tool to secure volumes, share capital-intensive investments and strengthen resilience against more volatile commodity cycles.

As an example, Canada’s Teck Resources and the UK’s Anglo American have worked for several months on a merger aimed at creating one of the world’s five largest copper producers, with a market capitalization exceeding $50 billion.

“The structure of a potential merger between these two groups remains uncertain and would likely be complex, but we believe a path exists toward significant value creation for both parties,” Jefferies analysts said, according to Reuters.

Reuters added that the deal could create “the world’s largest mining group, with a combined market capitalization close to $207 billion.”

Rio Tinto and Glencore already operate diversified and potentially complementary portfolios, including significant African exposure.

Glencore ranks among the leading copper and cobalt producers in the Democratic Republic of Congo through its stakes in several mining complexes in the country’s south.

In 2024, combined copper output from its Kamoto Copper Company and Mutanda mines reached 224,500 tonnes, while cobalt production totaled 35,100 tonnes.

Rio Tinto operates in Guinea in bauxite and iron ore, where its Simandou project entered production in late 2025 and ranks among the world’s largest iron ore developments.

The group also operates in South Africa and Madagascar through mineral sands and ilmenite activities.

In December 2025, the Anglo-Australian miner said it planned to raise between $5 billion and $10 billion through a portfolio review, aiming to divest non-strategic or underperforming assets and refocus on iron ore, aluminium, lithium and copper.
